I think the medical device which everybody has as a final goal as the utopia of med devices is the one like Star-Trek. is it called Tricorder? One that somehow scans your body and is able to immediately identify illnesses. We'll we ever get to see that? What would it use? X rays? among others i suppose.

Great question! We really are just looking for a sketch or other type of rendering. You don't need to get into the specfics of the inner workings of the device. We want an idea of what it might look like and something visual to help readers with the voting process. One step up from napkin sketch is perfect.
